Björn Kiencke Title of the paper Conception and Implementation of a Software Distribution to Facilitate the Us- age of an Energy Data Monitoring System Keywords Live System, Energy Data Monitoring, Remastering, Java, JEVis, Ubuntu, Kernel Abstract This report comprises the development process of a solution which offers energy data monitoring for testing and training. This kind of program is used to increase the energy efficiency of industrial companies and hence to implement the requirements of energy management systems according to standards like ISO 50001.The JEVis Data Monitoring System depends on several compo- nents, e.g. a database server. Therefore a huge overhead on configuration is demanded. In the thesis presented the approach of a live system to facilitate using an energy data monitoring system is taken. Furthermore, a program to simplify the remastering-process is designed.

However, during the recent decades especially non-renewable resources are running short and although renewable energy sources are on the rise, new technology can not close the gap as quickly. Moreover, political decisions contribute to this problem significantly which has lead to a dramatic increase of energy prices since the turn of the millennium. The price of oil can be taken as a good example for this and it is commonly accepted that the peak was already reached during the last years (cf. Kausch et al. 2011, p. 11). For industry, mother earth’s signs of exhaustion and the above mentioned lack of alternatives means facing the costly effects of this development. Therefore, energy efficiency has become the key word for companies CEO’s to get control over this problem. In addition, costumers get increasingly conscious about ecological sustainability during the method of production of a product. A promising way to realize a resource-optimized method of production of such a kind is the implementation of an energy management system basically enabling the company to monitor the energy the process needs in every production step over time. To implement a suitable energy management system companies are commonly advised by service providers. One of these is the Envidatec GmbH where this thesis was performed. For the purpose of analysis, control and surveillance energy data monitoring programs are used. In line with this thesis a modular software solution is dealt with. This implies a pedestrian and complex installation which is not appropriate for an - concerning this project - unskilled person. Within this thesis multiple concepts where established to create an easy way of testing allowing users to let the program run out of the box and by that enabling a broad audience to work with this software. Therefore, the aim of this thesis is the establishment of an energy data monitoring live system. For this a Linux distribution was remastered. This means, that the energy data monitoring application was integrated in the OS and further minor and major modifications were performed. 1 1 Introduction As an example of a minor modification the adaption in design and the addition of icons for easy handling of the system can be mentioned. Furthermore, major modifications enable the user to install the OS together with the ready to run monitoring software on a local drive. With respect to the hardware available this leads to a faster system and can be used for test and research purposes. Last but not least a continuously advancing development of this software shall be facilitated since this is an open source project. For this the remastering process is implemented in a self-programmed application to provide developers an easy and time-saving way of creating a new version. To relieve reading this thesis here is an overview of the contained sections. The second chapter gives detailed information about the motivation of implementing energy management systems. Furthermore it deals with background facts on the company, their monitoring software, issues of founding an open source community and subjects of live systems. The third and fourth chapter document the process of conception. This includes the procedure given by modern software engineering: generating use-cases, extracting requirements and specifying the design. Subsequently the next chapter is about the implementation containing explanations of the used programming techniques and examples of implementation in source code. Furthermore the results of the development are presented. The last chapter reviews the implemented solution and sketches out its advantages and disadvantages. Finally, the outlook section gives information about further steps, which are already planned. 2 2 Background 2.1 Motivation During the last years energy economic issues have become increasingly important for companies. Limited resources available and the growing demand for energy are leading to higher prices. In addition, political decisions have impact on the price of energy. Especially in Germany, companies are encouraged to optimize their energy consumption. The feed-in tariffs for renewable energies whose additional costs are known as EEG surcharge raise by 2013 up to almost 5:3 ct/kWh. The contribution of the industry to achieve the planned aims implies exploiting energy saving potentials. The Policy Report by the Fraunhofer Institute by order of the Federal Ministry for the Environment Nature Conservation and Nuclear Safety sees a reduction potential of 52 percent on final energy demand compared to the baseline. The major amount of 75 percent savings can be exploit by making use of cross-cutting technologies1 (cf. Boßmann, Eichhammer, and Elsland 2012, p. 18). An indicator for the success of the efforts is the energy productivity. It is defined by the consumption of primary energy on products and services in comparison to the gross domestic product. The reference for the derived statistic is set to 100 percent on the data of 1990. The German government is aiming to double the energy productivity until 2020 compared to 1990. As shown in figure 2.1 the value already improved by almost 50 percent. Considering the aims increased efforts are necessary. In particular the industry has to take activity for optimization. A common way to improve the energy efficiency is given by the specification ISO 50001. The process of implementing an energy management system (EnMS) according to this standard provides the tasks of monitoring, measurement, and analysis. There are certain good reasons using energy data monitoring software to implement this. The most important are the quantity of data samples 1Efficient steam and hot water generation as well as optimization of entire systems relying on electric drives.
